Dear community,
Is it possible with ParaView to group vtkImageData objects in a single file format? I would like to import a couple of regular grids (i.e. vtkImageData objects) as a single file, rather than as grid_1.pvti, grid_2.pvti, etc... Once imported I would like to simply select which grid to visualize (with volume rendering). I tried the following structures already: 1. vktMultiBlockDataSet containing N vtkImageData objects as child blocks. 2. vtkMultiBlockDataSet containing 1 vtkMultiPieceDataSet, which contains N vtkImageData objects as child pieces The first structure kind of works, but in order to visualize one vtkImageData I need to "Extract Block" and "Resample to Image", which doesn't result in the exact same image when doing volume rendering. The second structure mixes my vtkImageData into a single data object. I cannot do something like "Extract Piece". The main reason I want to have a single data structure containing all my grids is so that I can pass it to my Python CoProcess Catalyst pipeline. The number of grids can vary so I cannot simply hardcode the pipeline for a fixed number of grids. If there is a way to make this work, please let me know! Best, Jimmy
